Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
Energy absorption device as depicted in figs. 1 and 2, including absorbing balancing weight 5 and one or more absorbing rubber cushion 6, this
Embodiment uses four absorbing rubber cushions 6, and absorbing rubber cushion 6 uses absorbing silicagel pad.Absorbing balancing weight 5 is provided with four first peaces
Dress hole 5a, the upper end of absorbing rubber cushion 6 is connected with absorbing balancing weight 5 by the first installing hole 5a, and the lower end of absorbing rubber cushion 6 is connected to
Cover in the second installing hole 3a on 3 at the bottom of skeleton, and cover at the bottom of absorbing balancing weight 5 and skeleton, between 3, there is gap.
As shown in Figure 4 and Figure 6, absorbing rubber cushion 6 uses pure silicon glue material to make, and Main Function is by vibrating energy-absorbing, its
Natural frequency is the key parameter of energy absorption device, and its natural frequency adjusts two kinds of approach: one be by change silica gel formula and
Its special process processes and is adjusted its frequency, and two is the diameter of the endoporus 6a adjusting absorbing rubber cushion 6.The present invention uses second
The mode of kind, offers endoporus 6a on absorbing rubber cushion 6 vertically, regulates absorbing rubber cushion by regulating the size of endoporus 6a on it
The natural frequency of 6.The first cylindrical section 6b that absorbing rubber cushion 6 includes the most sequentially coaxially arranging, the second cylindrical section 6c, the 3rd
